We can guide you through the setup with MariaDB as well.
The setup of either MariaDB or MySQL will only guide you through creating a password and installing the server service into windows.
Unless I'm mistaken, neither installer will ask you to create a non-privileged user and/or a database. (It's been quite a while since I last set up a MySQL/MariaDB server on a Windows machine)
SAM won't even try to create it's own database. (Usually Database servers aren't accessed from an admin/root account, except for administrative & maintenance tasks. A normal user wouldn't have the permission to create a new database, though.)
You can either create a database using a graphical management tool you'll have to get first. (MySQL comes with MySQL Workbench if you use the All in One installer for the community/GA version found here: https://dev.mysql.com/downloads/windows ... r/5.7.html
- you only need one of the two downloads offered there, if the machine where you install it is always online, you can choose either, otherwise use the second - on the following page just click no thanks below the login/signup buttons)
I did a video guide for the setup a few years ago when you still had to download and install the server and the tools separately. You can most likely install everything with the default/typical settings these days. This will most likely install additional things that you don't need, but it doesn't hurt SAM either.https://youtu.be/kJU5f3nZYtI?t=5m20s
(At 5m20s MySQL Server and Workbench are installed and Workbench is started. From there on it guides you through creating a new database and user for SAM and reconfiguring SAM to use MySQL/MariaDB instead of Firebird. Everything in the 5 minutes before that is just downloading and installing MySQL Server and Workbench with custom/detailed settings, again unneccessary if you just use typical settings and memorize your root password)
Or you can do it using the commandline and using SQL (a structured language to ask a database for information or insert information into one) and the commandline tools that come with your database server.
Most people in the online radio community are afraid or even frightened of using the commandline. (Mostly copy and paste, but you will need to adjust the path to your system. Especially because the name of the MySQL folder has the version number that changes every few weeks in it)
If you'd like to try that, I'll be glad to give the instructions, but I won't bother to write that down if you're not interested.
